I can't produce the segfault, either.

Lyrics inside the piano staff would hit span bars, but you don't have any,
so the engraver should not be doing anything.
The back-trace, however, seems to say that the engraver is doing something.

When I put a debug print at span-bar-stub-engraver.cc:119
and run your file (with the engraver re-enabled) I never reach that line!
Mike, Maybe it is the empty \new Dynamics {} inside the PianoStaff in Jay's
score? A print at line 109 shows that LilyPond is considering the empty
Dynamics for inclusion in affected_contexts_. Maybe we are testing
de-allocated memory?
